1982 Map of Halfway Ridge

USGS Topo · Published 1986

About this map

Trinity National Forest defines the landscape of this region, where the steep drainages of Halfway Ridge and Oak Ridge converge on the remote Indian Valley. The map documents a sparsely populated wilderness characterized by critical water sources like Fir Root Spring, Sheep Camp Springs, and Sardine Spring, which likely served as essential stops for early travelers and forest rangers. The small settlement at Indian Valley Station sits at the junction of several gulches, including Green Gulch and Sheep Gulch, indicating its role as a local focal point for activity in the valley.
